Abstract: A nodular cast alloy, a casting made therefrom, and a production process therefor, which has a perlitic-ferritic microstructure for cast iron products and has a high strength combined with good ductility and toughness even in the cast state, including, as nonferrous constituents, C, Si, Ni, Mn, Cu, Mg, Cr, Al, P, S and normal impurities, characterized in that the nodular cast alloy in the cast state without subsequent heat treatment achieves a high static strength of a 0.2% offset yield strength of ?600 MPa and a tensile strength of ?750 MPa combined with good ductility of an elongation at break A5 of from 2 to 10%.

Abstract: An axial retention 4 of a roller bearing 1 in a support part 2 comprises a stop shoulder 7, disposed at an elastically or flexurally widenable portion 6 of the support part 2. When the roller bearing is pressed into the support part 2, the portion 6 widens. After the roller bearing has been pushed up to the shoulder 3, a reverse or return deformation of the portion 6 occurs, so that the stop shoulder 7 forms the axial retention 4 for the roller bearing 1.
